INTRODUCTION The OSMOMETER OSM-9 is a compact micro processor controlled analyzer for easy and precise osmolality tests in samples of serum, plasma, urine or other body fluids. The OSMOMETER OSM-9 makes the running of the osmolality test very easy. a) 100 μl of the sample are pipetted into a sample tube b) The sample tube is attached to the measuring head c) The measuring head is pushed down into the cooling chamber d) Now the measuring cycle starts automatically e) When the measuring is terminated, the measuring head returns to its upper position again, and the result is digitally displayed in mOsm/kgH2O The 1-point-calibration requires distilled water only, and is one of the most practical features of this analyzer. The calibration values are automatically calculated and stored in the microprocessor memory. The microprocessor control and built in electronic components with high long term stability make the OSMOMETER OSM-9 an analyzer of easy application and reliable results. 2. MEASURING PRINCIPLE The osmolality of a solution is a function of the number of particles - molecules and ions of the substances, which are solved in 1 kg of the solvent. The osmotic concentration or osmolality does not depend on the molecular weight of the solved substances. The solved substances influence several physical parameters of the solution and can be measured. For example: If the osmolality increases, the following parameters of the solution will change: - Osmotic Pressure increases - Freezing Temparature decreases - Boiling Temparature increases - Vapour Pressure decreases A very significant method to measure the osmolality in biological liquids is the detection of the freezing point of the solution. The relation of freezing point temperature and osmolality in diluted solutions is a linear function, so that the basic cryometric rule says: The lowering of the freezing point of the solution compared to the freezing point of the pure solvent is proportional to the osmolality of the solution. The proportional coefficient - called the cryometric constant K - for water is 1,858deg x kgH2O/Osm. During the measuring process the sample is continuously cooled down from ambient to the super cool temperature of -7°C - still being liquid. Then the crystallisation is initiated and the temparature now raises to a maximum, which equals to the freezing point, corresponding to the osmolality of the sample. The typical sample temperature course during the measuring cycle shows fig. below. 4 O C tk t (Min.) 2 1 READY i ti - temperature at which the crystallization in the super cooled solution is initiated tk- lowering of the freezing temp. of the solution according to the osmolality The general equation of tk to osmolality is influenced by several nonlinear functions of the electronic and mechanical components of the analyzer. These values are calculated during the factory calibration and stored in the microprocessor memory in Osmometer OSM-9. 3.

It’s earth continuity plug have to be plug into 230V/50-60Hz. THE OSMOMETER OSM-9 MUST NOT BE IN USE IF THERE IS NO SURE IN CASE OF CONTINUITY EXTERNAL SAFETY CABLE IN THE INSTALATION OR IT’S CIRCUIT. you must not take off the osmometr case – it threats with current stroke in case of osmometr is wet because of water or steam condensation (f.e. just after removing from cold to warm room - do not use the Osmometer OSM-9); if there are any visible damage that could be the result of falling down - do not use the Osmometer OSM-9; 6. SAMPLE COLLECTION AND PREPARATION The sample collection and preparation is always according to inside procedures of your Diagnostic Laboratory and please, apply below information. Pipette 100 μl sample into a dry and clean sample tube. Pay attention that no droplets remain on the inner side of the sample tube and that no air bubble is enclosed in the sample. We recommend pipette fixed-volume 100 l (precision error MAX 0,9%; repeatability error 0,4%). Sample tubes OSMO-KRIO is single use only with special crystal seeds. Maximum storage time of sample tubes OSMO-KRIO is 1 year from the purchase date. Sample tube OSMO-KRIO could be storage in dry place, without the sun operation, temperature from 10°C to +40°C. 6.1. Warning: infected sample treatment NOTE!: Work only using single use gloves The thermistor probe is made from glass – make sure that is always safe. The thermistor probe could be damage by mechanical action – cracking or breaking (by hitting or the instrument falling down) that could effect in user injuring. Always after infected sample measurement - rinse the measurement unit by special agent using in disinfection and then rinse all with big amount of distilled water. 6.2. Human bodyfluids sample 7 NOTE!: Work with human bodyfluids sample only using single use gloves. 7. MEASURING HEAD Osmometer OSM-9 – measuring head 7.1. MEASURING HEAD OPERATION The sample tube OSMO-KRIO is carefully moved from below onto the mandrel (1) until the retaining spring (4) engages. The thermistor probe (2) entering the sample tube and the stirring wire (3) must not get damaged while positioning the sample tube and should not be touched, when sample tubes are attached or removed. The measuring head is lowered into the cooling chamber by applying pressure to the pressure point (N). The measuring head is mounted on the slide bar (5) as it is being lowered. The measuring head is then held in bottom position electromagnetically. The electromagnet is ON only after go into MEASUREMENTS or CALIBRATION or SERVICE INFORMATION. 8. Switch on the OSMOMETER OSM-9 !!! Before power ON the Osmometer OSM-9 always dry the cooling chamber by lintless tissue. Power ON the instrument using switch located on back side of the instrument. Wait 5 min. as measuring head will be ready. The display will show the passing time as soon as the cooling chamber reaches work temperature. 2 0 1 1 . 0 6 . 3 0 2 3 : 5 9 : 5 9 O SMOME T E R S L AME D Gmb H * G E RMAN Y V E R : 8 0 0 G 1 1 0 7 0 1 : 2 0 MOD E Fig. 1 Active key: MODE CALIBRATION – READY FOR CALIBRATION inform that Omometer OSM-9 is in calibration mode. 8 C A L I B R A T I ON R E AD Y F OR C A L I B R A T I ON MOD E Fig. 4.2 Active key: MODE Rinse the thermistor probe and stirring wire using distilled water. Dried very carefully thermistor probe and stirring wire to avoid damage or deformation and fibers leaving. Then go to calibration according to p.8.1 CALIBRATION. NOTE! Leaving fibers at the thermistor probe could cause sooner crystallization. NOTE! Deformed stirring wire could not initiate the crystallization. 8.1. Calibration The main function of the calibration is to do the correction of measurement block characteristics. The change of these characteristics is on as natural process of thermistor probe “getting older”. Pipette 100 μl calibration solution sample (distilled water) into a dry and clean sample tube OSMO KRIO. Pay attention that no droplets remain on the inner side of the sample tube and that no air bubble is enclosed in the sample. Sample tube OSMO-KRIO with sample inside is carefully moved from below onto the mandrel until the retaining spring engages. The thermistor probe entering the sample tube and the stirring wire must not get damaged while positioning the sample tube and should not be touched, when sample tubes are attached. Pressure to the pressure point (N) and lower the measuring head into the cooling chamber. The measuring head is then held in bottom position electromagnetically and measurement is started with displaying actual sample temperature.

The calibration correction is done automatic and then it’s counted and corrected value will be displayed: 0 mOsm/kgH2O. 9 Take off the sample tube carefully- to avoid the thermistor probe and stirring wire damage. Dry the thermistor probe and stirring wire by lintless tissue. The blinking CURSOR BAR, under ZOOM frame, points sample defrosting. Do not take off the sample tube from measuring head – in case not to damage the thermistor probe. NOTE! When the power is switched off, the memory will lose the calibration value! So every time when the osmometer is switched on, it requires a new calibration to compensate for the long term drift of the thermistor probe parameters. 9. MEASUREMENTS 9.1. Measurements Just after calibration, the Osmometer OSM-9 automatically goes to mode: MEASUREMENTS, READY FOR SAMPLE.

THIS CORRECTION IS ON – AT MIN. -4°C SAMPLE FREEZING. Take off the sample tube carefully- to avoid the thermistor probe and stirring wire damage. Rinse the thermistor probe and stirring wire using distilled water. Dried very carefully thermistor probe, stirring wire to avoid damage or deformation and fibers leaving. See point: MEANING OF DISPLAYED ANNOUCEMENTS if at the display appear E - ... The measurement result with an terror signalisation is not in memory. Go to the next measurement without any additional action. The sample tube with sample put on the thermistor probe and stirring wire assembly. Put the sample tube into the cooling chamber by pushing the measurement head. Please, follow above instruction to execute next measurements. 9.2. Stop during measurments You don’t have to power off the Osmometer OSM-9 if the break in measurements in not over 90min. Put a clean sample tube on cleaned and dried thermistor probe and stirring wire. The second one put into the cooling chamber – it makes the frosting process slower. NOTE! You have to power off the Osmometer OSM-9 if the cooling chamber is strong frosted (the symptom is getting stuck of sample tube inside the cooling chamber). Then you have to wait as the frost will melt and dry the cooling chamber with lintless tissue. Just after that action go to p. MEASURING PREPARATION. 9.3. Measurements finishing After finishing all measurements, power off the Osmometer OSM-9 with power switch. Clean the thermistor probe and the stirring wire with distilled water and dry carefully. Empty sample tube put on the thermistor probe and stirring wire. Dry a defrosted cooling chamber with lintless tissue and put into the empty sample tube. 11 10. OPERATION NOTE 10.1. Liquid dosage We recommend pipette fixed-volume 100 l (precision error MAX 0,9%; repeatability error 0,4%). 10.2. OSMO-KRIO sample tubes Sample tube OSMO-KRIO is single use only with special crystal seeds. Maximum storage time of sample tubes OSMO-KRIO is 1 year from the purchase date. Sample tube OSMO-KRIO could be storage in dry place, without the sun operation, temperature from 10°C to +40°C. 10.3. Calibration and control solution Calibration solution 0 mOsm/kgH2O – distilled water APPLICATION see point. 8.1. Control solution 400 mOsm/kgH2O (osmolality standard) is a compound of distilled water and NaCl that has fixed osmolality. The amount of NaCl is 12.687g NaCl/kgH2O and is used to Osmometer OSM-9 measurements control. 10.4. Control/test measurements Introduce with pipette the 100ul control solution 400mOsm/kgH2O sample to the clean and dry sample tube. During pipetting: - avoid making air bubble - do not spill the sample at the sample tube wall Then go to the p. MEASUREMENTS 9.1. The 400mOsm/kgH2O control solution is available in single use ampoules. After ampoules opening and making control measurements cycle – do not store the rest of control solution. THE CONTROL SOLUTION IN OPEN AMPOULES WILL CHANGE IT’S OSMOLALITY WITH TIME AND YOU MUST NOT USE IT AS OSMOLALITY STANDARD. 10.4.1 . Test of measurement precision Test of measurement precision you should according to below information. Do 3 calibration test measurements according to p.5 MEASURING PREPARATION after power ON the Osmometer OSM-9. Use the calibration solution 0 mOsm/kgH2O – acceptable border error ±1 mOsm/kgH2O. If this condition is not fulfill – you must repeat measurement. Next do the series of 10 control solution measurements ( control solution with known osmolality value that is settled in reference method). You could count the osmometr precision error on the base of achieved results: D [%] = (VS - VN ) / VN x 100% VS – mathematic average value from achieved series result VN – expected value – nominal value of using osmolality standard The precision should be no worse than ±0,5%. 12 10.4.2 . Test of measurement reproducibility Test of measurement reproducibility should be done as below: You could count the reproducibility error on the base of measurement results achieved in 10 measurement series according to p.9. P [%] = SD / VS X 100% SD – square standard deviation from the series of achieved results SD V V / n 1 2 1 S VI – next value of achieved measurement result VS – mathematic average value from achieved series result n - the number of measurements in series The reproducibility should be better then ±0,5%. 10.5. Information and practical hints Keep the cooling chamber dry. Especially dry the cooling chamber before you switch on the analyzer so that residual water cannot freeze and interrupt the measurement. After having measured all samples and defrosted the cooling chamber, it have to be always dried by lintless tissue. After having measured all samples switch off the power. Then rinse the thermistor probe and the stirring wire with distilled water and dry both of them carefully. Empty sample tube attached on the rim of the thermistor probe (during pause in measurements or after measurements) make the thermistor probe and stirring wire safer. Additional there is lower possibility of incidental damage. The empty sample tube, inserted into the cooling chamber, protect the cooling chamber against contamination that makes measurement impossible to execute. During the measuring cycles a thin layer of hoar-frost covers normally the cooling chamber. If this layer begins to turn into ice, it could jam the sample tube. In this case the osmometer has to be switched off for defrosting and after that it should be cleaned with lintless tissue. Preparing the Osmometer OSM-9 to work is then according to point 5. MEASURING PREPARATION. The empty sample tube inserted into the cooling chamber, during measurements pause, will make chamber frosting much more slower. After long break in instrument work we recommend before measurement to rinse the thermistor probe and stirring wire with distilled water and dry with lintless tissue. In case runner contamination that could be observed Contamination of slide bar. Signs: slow or not full upwards movement of measurement head. Action: clean the slide bar with alcohol and clean contamination with lintless tissue. Repeat it several times to the moment of achieving smooth in measurement head movement. The slide bar cleaning ONLY with power off the Osmometer OSM-9. Osmometer cleaning. Power OFF the Osmometer OSM-9 before any clearing action. Clean the osmometer case with smooth and wet cloth. Do not use any organic solvents. You can use soft detergent to remove of strong contamination and then clean it with wet cloth and dry. 13 10.6. The stirring wire replacement The problem with sample freezing could be a result of stirring wire deformation. Stirring wire changing: unscrew the stirring wire screw with fingers and remove deformed stirring wire from the measurement head. Mount a new stirring wire at the axis screw in such way that after it’s mounting in the measurement head the bending end of stirring wire is in the direction of the thermistor probe. 11.
